Abstract
The utility model relates to an electric bicycle middle supporting stand with a locking function, which comprises a stand and a rotating shaft connecting plate mounted between a front triangular frame and a rear triangular frame, wherein a locking plate is fixedly arranged in the front of a front end plate of the rotating shaft connecting plate, the locking plate is hinged with a swing arm via a hinge, a lock bolt is fixedly mounted on the stand, and a hook fabricated at the front end of the swing arm positions and hooks the lock bolt. The middle supporting stand is convenient and fast in use and skillful in conception, increases stability of electric bicycles in positioning states, resolves deflection of the conventional middle supporting stand, prevents electric bicycles from inclining and overturning, and achieves more reliable locking effect by matching with the original locking spring.
Description
Technical field
The utility model belongs to electric automobiles, a car ladder in especially a kind of battery-driven car with lock function.
Background technology
Battery-driven car is to use the comparatively general vehicle at present, for people's trip, loading, shopping provide great convenience.Because battery-driven car is a driven by power, battery has been installed onboard, and common design has vibration-proof structure.Because battery is heavier, a car ladder during the car ladder of battery-driven car adopts mostly is to improve the stability of battery-driven car.Car ladder generally is packed on the rotating shaft connecting panel between Vee formation vehicle frame and the preceding triangular frame in the existing battery-driven car.A car ladder is better than single car ladder and two car ladder stability in this, but also exist following defective: because the general weight of battery-driven car is heavier, a car ladder seems less with ground-surface Area of bearing in making, the terraced rear stability of getting on the bus is relatively poor propping up, cause have slightly tilt or the situation of vibrations under, a car ladder positioning in being very easy to cause and make the battery-driven car tipping.This situation seems still for serious at the load-carrying battery-driven car.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a car ladder in a kind of battery-driven car with lock function is provided, and this car ladder can prevent effectively that battery-driven car is unsceptered topples over.
The utility model solves its technical matters and is achieved through the following technical solutions:
A car ladder in a kind of battery-driven car with lock function, comprise the rotating shaft connecting panel of installing between car ladder and preceding triangular frame and the Vee formation vehicle frame, front portion at rotating shaft connecting panel front end-plate is fixed with a lockplate, on this lockplate, adorn a swing arm by the bearing pin hinge, install a lock on the car ladder, this lock is hooked in the made crotch location of the front end of swing arm.
And, a retracing spring is installed between the rear end of described swing arm and the lockplate.
And, described car ladder is contained in the rear portion of rotating shaft connecting panel front end-plate by the connecting panel hinge, concrete structure is: the rear portion dual-side at rotating shaft connecting panel front end-plate installs connecting panel by the binding bolt symmetry respectively, and the front portion of this connecting panel installs the car ladder, and lock is packed on the connecting panel.
Advantage of the present utility model and beneficial effect are:
1, prop up the car ladder in the hinge dress on the rotating shaft connecting panel of car ladder between Vee formation vehicle frame and preceding triangular frame in this, and symmetry installs connecting panel on the rotating shaft connecting panel, installs the car ladder on this connecting panel; Another side at the rotating shaft connecting panel also installs a lockplate, adorn a swing arm by the bearing pin hinge on this lockplate, the made crotch of the front end of this swing arm can be located and be hooked the lock that is packed on the car ladder, thereby realized that centering props up the artificial locking of car ladder, improved the stability under the battery-driven car positioning states, the positioning problem of a car ladder has been avoided the battery-driven car tipping in having solved.
2, the swing arm rearward end that car ladder is installed in this can be connected with the retracing spring that lockplate is installed, and the crotch of swing arm leading section can or be mounted with the lock automatic release, and is convenient to use, is skillfully constructed.
3, car ladder can be used with former locking spring in this, and locking effect is more reliable.
Description of drawings
Fig. 1 is the electromobile frame simplified schematic diagram;
Fig. 2 be of the present utility model in car ladder enlarged front view is installed;
Fig. 3 is the right elevation of Fig. 2;
Fig. 4 is the left view of Fig. 2.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A car ladder in a kind of battery-driven car with lock function, triangular frame 1 and Vee formation vehicle frame 5 mode by rotating shaft connecting panel 4 is connected and on the battery-driven car that shock absorber 2 is installed on the vehicle frame, referring to Fig. 1 before being applicable to.
In the present embodiment, rotating shaft connecting panel between preceding triangular frame and the Vee formation vehicle frame is a prior art, the welding of its front end-plate and preceding triangular frame installs, lower back panel welds with the Vee formation vehicle frame and installs, install a plate 7 by binding bolt (not having label) symmetry respectively at the dual-side with preceding triangle frame shaft connecting panel front end-plate rear portion, the front portion welding of this connecting panel installs car ladder 3.Be fixed with a lockplate 10 in the welding of the front portion of rotating shaft connecting panel front end-plate, adorn a swing arm 8 by the bearing pin hinge on this lockplate, install a lock 6 on connecting panel, the made crotch of the front end of swing arm can be located and be hooked this lock; In order to make the made crotch of swing arm can self-orientation hook lock and the location discharges lock, between the rear end of swing arm and lockplate, a retracing spring 9 is installed.
In the present embodiment, the car ladder is connecting panel and the rotating shaft connecting panel hinge dress that adopts symmetry, and the car ladder can be the U font shown in the present embodiment accompanying drawing, and a car ladder is attractive in appearance in having guaranteed like this.Also can adopt the direct hinge of car ladder both upper ends thereof is contained on the front end-plate of rotating shaft connecting panel, its result and function are basic identical.
Principle of work of the present utility model is:
After propping the car ladder, under the effect of retracing spring, the leading hook of swing arm automatically locks lock, and a car ladder can positioning in making; Make crotch after lock breaks away from the release swing arm, can discharge the car ladder and drive to advance.
